Board <br /> Central Valley Region <br /> 3443 Routier Road, Suite A <br /> Sacramento, CA 95827-3098 <br /> Re: Addition to the Waste Discharge Requirements, Tri <br /> Valley Growers, Plant T, 26200 Nowell Road, Thornton, <br /> CA. <br /> Dear Robert: <br /> WaterWork has been performing a subsurface investigation at Tri <br /> Valley Growers Thornton Plant, We have defined a dissolved <br /> gasoline plume near the fork-lift shop (see attached Figure) and <br /> are now ready to begin groundwater cleanup activities. <br /> We have proposed to Darlene Ruess of San Joaquin County and Tom <br /> Peltier of your office installing a pump and treat remediation <br /> system. The system would consist of a low flow pump ( 1-2 gpm) <br /> and two 200-pound carbon absorption filters which would operate <br /> on a 24-hour basis year-round. We are requesting permission to <br /> reclaim the treated water by discharging on-site. The treated <br /> water would be pumped to a storm drain that is connected to Tri <br /> Valley' s waste collection system. This water will ultimately be <br /> discharged on the facilities fields. <br /> We would like to begin installation and operation as soon as <br /> possible. Please notify me of any requirements or additional <br /> information needed to make this addition to Tri Valley's existing <br /> Waste Discharge Requirements. <br /> Respectfully, <br /> WaterWork <br /> ,o,Wi� -,"- , <br /> Bill Channell <br /> Senior Geologist <br /> BC/ktt <br /> Pc: Darlene Ruess '. <br /> Tom Peltier <br /> Juan Quijano <br /> 1710 MAIN STREET • ESCALON, CA 95320 • (209) 838-3507 <br /> FRESNO.CA(209) 222-3495 0 RENO.
